“…Based on our observations, we considered that the shading effect of herbaceous vegetation should be considered too, as it occurs earlier than canopy closure. As C. bulbocodium is a weak competitor for light (Kulikova et al 2019;Bogoslov et al 2021), the development of the surrounding herbaceous vegetation can limit its growth, assimilation capacity as well as its tness. In accordance with these studies we also found that the number of detectable individuals was negatively affected by the surrounding dense vegetation and also, that capsule production success was negatively affected by increased understorey plant cover.…”

“…In our study we considered both actual and lagged weather parameters to study their effects on population dynamics of C. bulbocodium. This is because studies involving geophytes mostly focus on their growth, reproduction and phenological changes in response to the weather parameters and light conditions of the actual year (Eppich et (Kulikova et al 2019), the effects of the surrounding vegetation should also be considered, when population dynamic is studied. For this purpose, in our study we also aimed to gather information about the effects of the biotic factors characteristic of the study site.…”

Due to their complex life-cycles geophytes are often neglected or mistreated during monitoring and conservation activities, despite they are important elements of early-spring communities. Their life-cycle is often strongly affected by weather parameters, i.e. temperature, precipitation, and light, but the main and combined effects of these parameters are often contradictory and show high intra-annual variability even within species. Deeper knowledge about the biotic and abiotic factors affecting the population dynamics of geophytes is needed to support the designation of evidence-based effective conservation plans. In our study we aimed to explore the link between weather parameters and population dynamics of Colchicum bulbocodium Ker-Gawl., an endangered and strictly protected geophyte. We monitored three phenological phases (flowering, assimilation, fruiting) of in total 1,069 individuals in Hungary, in permanent plots for six consecutive years. The effects of temperature- and precipitation-related weather parameters, as well as plot characteristics on the response variables were studied with generalized linear mixed models. Our results showed that phenology of C. bulbocodium was more strongly related to the actual weather than to the lagged effect of weather parameters of the previous year. Increasing temperature and lack of cold periods had negative effect on all phenophases. We highlighted that population estimation based on the number of flowering individuals in a single year can underestimate population size by 40–83%. Monitoring in years following wet and cold springs and cold winters could increase the accuracy of population estimations of the flowering individuals, while surveys in cold springs can estimate reproduction success the most accurately.

The article presents the results of the vitality structure analysis of 23 natural cenopopulations of Colchicum bulbocodium subsp. versicolor in the Lower Volga region in the years 2014–2019. The viability of cenopopulations within the studied region varied greatly over the years of monitoring, from 0.45 to 1.51. Cenopopulations in the northeast of the Lower Volga region, compared to southwestern cenopopulations, exhibited lower vitality index, greater instability and a wider range of variability of the latter parameter. Also, most morphological characters poorly correlated with one another. A high correlation was revealed only between two characters, and a medium correlation only in six pairs of characters. The largest number of significant-correlation relationships was registered for the plant height and diameter, the length and width of the lower leaf, and the length of the marigold. Based on the IQ parameter and the Q criterion, the absolute majority of cenopopulations were prosperous in all the years of monitoring. The depressive state was found only in some cenopopulations and only in certain years of monitoring (mainly in 2018). Considering that, compared to other years of monitoring, in the spring of 2018, the average temperatures during the period of the subspecies’ active vegetation and flowering were extremely low, we suggested that it could have resulted in extreme growing conditions for the subspecies in the studied region and, consequently, a decrease in vitality of cenopopulations.
